Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
EC50 (72h) > 29.1 mg/L and EC10 (72h) = 5.24 mg/L (measured) for Pseudokirchneriella subcapitata (OECD 201)
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 5.24 mg/L
Additional information
One study investigating the toxicity of Reaction product of fatty acids C14-18/C16-18 unsaturated with dihydrogendioxide and ammonia to freshwater algae is available. The study was performed according to GLP and OECD guideline 201 using Pseudokirchneriella subcapitata as test organism (Institut of Industrial Organic Chemistry, 2012). The substance was tested under static conditions at measured concentrations of 1.77 to 29.1 mg/L. The 72h-EC50 is determined to be > 29.1 mg/L and the 72h-EC10 is determined to be 5.24 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
